Application led March 29, 1913.

To all i0 wm t may concern:

Be it known that l, WILLIAiiI J. DiiIscoLL, a citizen of the United States, and a resident of Boston, county of Suffolk, and State of lilassachusetts, have invented an lmpiorement in Dispensers, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to dispensersfor liquids.

One of the objects of the invention is to provide a dispenser which shall be of simple construction and efficient in operation.

The various features of my invention will best be understood from the following description taken in connection with the accompanying drawings of a dispenser embodying one form of my invention and selected for the purpose of illustration, Ythe scope of the invention being more particularly pointed out in the appended claims.

ln the drawings: Figure 1 is a front elevation. of an apparatus embodying a preferred form of the present invention; Fig. is vertical section on line 2--2 of Fig. 5; Fig. 2 is a side elevation of the apparatus shown in Fig. 1; Fig. l is a horizontal section taken on line 4l-l of Fig. 1; Fig. 5 is a plan view of the apparatus shown in Fig. 1; Fig. (S is a vertical section on line G-G of F 1; Fig. 7 is a detail of the connection.

between the counter wheels and their operating shaft.

ln the accompanying drawings7 the ini'cntion is shown embodied in an apparatus intended. more particularly for disbr-weragc.. rlfhe body 2 of the apmay be supported in any suitable manne;` as, for example, upon legs Ll. ln the todi: 2 there are provided a chamber G and two containers 8 and 10. intermediate the containers 8 and 10, there is provided a valve. As shown in Figs. 2, di and 6, the rotary core 12 of the valve is provided with two recesses 1li. and 16 extending from the 'ieriphery of said core inwardly and separated by the preferably curved partition 1S.

The recess 16 communicates at all times with the passage 2O of the discharge nozzle 22 by means of a passage 2e. A circular plate terminating in a handle 2G is attached in any suitable manner as by screws 25 '25',

Fig. 2, to the exposed upper surface of the core 'l2 whereby to rotate said core.

W'ith the core in the position shown in Specification of Letters Patent.

serial No. 757,521.

Figs. 2 and 4, the recess 16 is in communication with a passage 2S leading from the container 8, while the recess 14 is in communication with passages 30 and leading from chamber 6 and container 10, respectively. lt will thus be seen that in this position of the parts, liquid contained in the chamber 6 will flow through the passage 30, recess 14- and passage 32 into the container 10, while any liquid contained in the container 8 will be free to flow out of said container through the passages 2S and 24- into the passage 20 of the nozzle 22 and be discharged from the apparatus. By turning the Valve core 12 contra-clockwise, the recess 14k may be brought into communication with the passages 28. and 30 of the container 8 and chamber 6, respectively, and the recess 16 into communication with the passage 32 leading from the container 10. ln this position, the liquid which had previously flowed from the chamber 6 into the container 10 will be discharged from the latter through the passages 32 and 24 and the nozzle 22, and liquid will simultaneously flow from the chamber 6 through the passage 30, recess 141 and passage 28 into the container 8. It will thus be seen that in the present apparatus one container is being replenished while the other is being discharged and that one container may be always provided with liquid ready to be dispensed.

It is desirable in apparatus of this kind that successive dispensing operations can take place in rapid succession. To this end, it is necessary that the discharge from one container and the replenishing of the other shall be effected rapidly, and the present invention contemplates the provision of means to this end. lt will be noted that the passages 80, 32 and 28 are of relatively large diameter and that their length corresponds to the full height of the chamber (l and of the containers 10 and 8, and that the recess 14 represents a relatively large section of the core 12 of the valve and that its height is equal to the full height of the passages 28, 30 and 32. lt will thus be seen that the repleiiishing of a container will take place very rapidly, the operation being practically instantaneous. It will also be noted that the recess 1G represents a large section of the core 12 and that its height is equal to the height of the passages 28 and 32. Also that the passages 2st and 20 are very capaeious, so that the discharge of the contents of a container is also effected very rapidly.

In machines of this kind, where one' container isbeing replenished while the other is discharging, this operation being effected through a common valve, it might happen 5 that unless the replenishing of a container take place as rapidly as its discharge, the operation of the valve as soon as the discharge from one container is completed may result in that container which is being replenishedwhile the other is being dis-- "charged, not receiving its full quantity, so that vupon reverse movement ofthe valve the full quantity called for will not be dispensed. The present invention contemplates means i to meet thisfdifticulty and to this end, as Vone 25 as the discharge Vofthe contents of a container has taken place without any danger that the other container will not have been replenished to the extent desired. This is a Vto Ybe operated very rapidly, the Ydispensing operations following each other in unbroken suceessionrif necessary without any danger that the proper quantity will not be dispensedvin every instance. No wait between successive dispensing operations is required.

The bottom surface 34 of the containers 8 andl l0 and that of the passages 28 and 32 will preferably be inclined downwardly toward the valve so thatthe full quantity will be 'discharged from said containers and there will be no drip, see Fig. 2. lThe bottom sur- 'i face 3G f the chamber 6 may also incline downwardly toward said valve.

The containers 8 and 10 are closed in any suitable manner herein by two threaded plugs 88, 3S provided with recesses 40 in l their upper surfaces.Y By introducing any Y suitable implement intosaid recesses, said `plugs may be readily unscrewed and re- 59 moved to give access to Lsaid containers for cleansing or any other purpose and as readilyreplaced. Suitable vents may be pro- Vgreat advantage as it enables the apparatusV videdY for Vthe containers S and l0, said ventsV herein consisting of shorttubes 42 closed at theirY upper ends', provided with lateral openings and screw-threadedV or otherwise secured in circular openings passing through f the top walls ofthe passages 2S and 32.

The core 12 ofthe valveV isf held in posi- @ation in the valve chamber by Vrods 44 roc Vtatably Ymounted in lvertically disposed re-V v 'I "fcesses 4GY provided in bosses v disposed `at either'side ofthe valve`V chamber and preferably integral with-the walls 'of theilatter.V Saidrodsiare each-provided with a laterally projecting head 48 adapted to overlie the upper surface of the handle plate E25. Springs 50 surrounding said rods in the lower enlarged portions of said recesses 46 press with their upper ends against abutments 52 in said recesses and downwardly upon pins 54 passing through said rods 44 adjacent their lower ends, said springs thus tending to draw the laterally projecting portions of the heads 48 of said rods down- 75 wardly into contact with the upper surface of the plate 25.

The beverage or other fluid to be dispensed may be introduced in any suitable manner into the chamber G. Said chamber may be 30 connected directly to the receptacle containing the beverage or liquid. For example, if coffee is to be dispensed, the coil'ee urn in rwhich the coffee is prepared may be connected directly with said chamber G so as to communicate therewith or said apparatus may be applied directly to the urn for that purpose.

It is often desirable to dispense beverages or other liquids from the bottle or other receptacle in which they are originally put upA or received. Thus it may be desirable to dispense whisky or other liquors from the original bottle, or milk or cream from the original jar, and the present invention centemplates means whereby this is rendered possible. To this end, there may be provided in the top wall of the chamber G a circular opening having its walls screwthreaded to receive a screw-threaded circular 10e disk-shaped plug 5G. Recesses 57, 5T may be provided in the plug to facilitate its removal by mea-ns of a suitable implement. This plug 56 is provided with a central opening herein circular for receiving the reduced 10a circular portion 58 of what may bc conveniently termed a socket member (30, the shouldered portion 62 of which may rest upon the upper surface of the top wall of the chamber 6, (see Fig. (S). The upper enlarged portion of said socket member (SO is preferably provided with an inner rubber sleeve 62% rlhis sleeve has a circular perforation which registers with a similar circular perforation provided in the wall of the socket member 60 and into which there is screw-threaded a metal plug 64, said plug being preferably screwed in suiiicicntly to .have its inner face Hush with the inner surface ofthe rubber sleeve (32a. There are 120 provided in the walls of the rubber sleeve 62 and of the socket member G0, respectively, two registering circular openings adapted to receive a plug GG which is screwthreaded into the wall of a circular opening 325 provided in a sustaining member 68 suitably Vmounted vonV the frame of the machine.

Y In practice the screw-threaded plug 66 having been unserewed sulliciently to with- Af draw it froinengageinent with the opening 1150 provided in the wall of the socket member G0, said socket member is withdrawn from the apparatus and is slipped on over the neck of the bottle or of the receptacle containing' the liquid to be dispensed. The socket member with the neck of the bottle therein is then replaced in the apparatus in the position. shown in Fig. G, the bottle being thus reversed and a part of the contents flowing into the chamber G, the flow being checked when the level of the liquid in the chamber G rises to the level of the lower open end of the circular portion 58 of the socket member 60 as will be readily understood. The plug` 00 is now screwed in inwardly until the neck of the bottle is firmly clamped in said socket member 60. The plug (5f-l prevents the rubber sleeve G2 from yielding in response to the clamping action of the plug 0G, and as the neck of the bottle is a close fit in the rubber sleeve the connection of the bottle with the socket member 60 is substantially air-tight.

lt will be apparent that the sustaining members G8 andplugs 011 and 0G might be dispensed with, but they exemplify a conrfenient means of securing the bottle in place in the apparatus so that it and its contents cannot be tampered with, the plugs G4 and' 06 being to this end provided with openings 72, 74 to be engaged by a correspondingly constructed key, whereby said plugs can be turned. Disk-shaped plugs having different size openings and socket members of different sizes may be substituted for the diskshaped plug 50 and socket member G0, respectively, to enable receptacles of different sizes to be used.

The invention may include means for varying or regulating the amount of liquid delivered to the container. One convenient form of such means will now be described.

lt will be apparent that in the form of the invention illustrated, the liquid will rise in the containers 8 and 10 to the level of the lower edge of the circular portion 58 of the socket member 00 and no higher. Hence by raising and lowering the socket member 60, the amount of liquid delivered to the containers 8 and 10 and dispensed by the apparatus can be regulated or varied as desired. To this end, the sustaining member 08 is provided with two projecting lugs 76, Fig. 5, in which are secured, as by nuts 7 8, the upper ends of two rods 80 rigidly oined at their lower ends by a cross-head 82, FiO, 1. To the under side of this cross-head are pivoted at 84 the ends of two links 86 having their other ends pivoted at 88 to nuts 90, 92 which are in screw-threaded engagement with right-handed and left-handed threads 9%-, 96, respectively, of a screw 98 mounted for rotation in twoboss bearings 100 projecting from the inner faces of the two diametrically opposed legs f1 of the machine.

Said screw is secured against longitudinal movement in said boss bearing in any suitable manner. 1t will be apparent that by turning said screw 98 in one direction, the nuts 90, 92 will be caused to approach each other and the socket member (30, with the receptacle supported thereby, will be raised, while by turning said screw 98 in the opposite direction, the nuts 00, Y92 will be separated from each other and said socket member and receptacle lowered. Any suitable means may be provided to rotate said screw, but in the present instance, in order to prevent its operation by unauthorized persons, the exposed end 102, see Fig. 3, of the screw 98 is provided with recesses 101i constructed and arranged to receive the same key that is used for turning the plugs G-it, 0G, so that said key may be used for operating said screw as well. To facilitate the vertical adjustment of the socket member- G0 to cause the amount of liquid desired to flow into the container 8 or 10 and be dispensed therefrom, one of the rods 80 may be provided with a scale 100, as shown in Fig. 1, divided into ounces and fractions thereof, for example, and a fixed index 108 attached in any suitable manner to the frame of the apparatus may be provided to cooperate with said scale, which latter will be graded in such manner that when, in raising or lowering the socket member G0, a division of said scale is brought into coincidence with said fixed index 108, the measure or amount of fluid marked opposite said division on said scale will be delivered to the container.

1f desired, vertically extending longitudinal openings 110 may be provided in the walls of the containers 8 and 10, said openings being closed by glass windows to enable the height of the fluid contained in a container to be observed.

Preferably, means herein exemplified by a counter will be provided to indicate or register the number of portions dispensed by the apparatus. Such a counter is shown in Figs. 5 and G as mounted in a bracket 112 secured to the upper surface of the body of the apparatus, as by screws 113, and having its arms 11-1- projecting forwardly over the plug 12. Said counter comprises the usual wheels 116 serving to indicate the units, tens, hundreds, thousands and tens of thousands, each provided upon its periphery with the numerals 1, 2, 3, 4, 5, G, 7, 8, 9, 0. All of said wheels excepting the unit wheel, are loosely mounted on a shaft 118, Fig. 7 mounted in bearings provided in said arms 1111 of the bracket 112. The unit wheel is rigidly mounted on said shaft. rEhe ends of the shaft 118 project through the arm 114 and are each provided outside of the adjacent arm with a gear wheel 120 loosely mounted op said shaft. Each of the gears 120 is provided with a lateral recess 122, see Fig. 7, adapted to receive a ratchet wheel 124 rigidly mounted on the shaft 118. Nithin said recess 122, there is pivoted'to the gear 120 at 126 a pawl 128 maintained in engagement with the teeth of the ratchet 124 by a spring 130 attached to the gear 120 at 132 within the recess 122.

The above-described construction is the same in the case of both gears 120 and from the description given taken in connection with Figs. 5 and 7, it will be apparent that when either gear 120 is rotated in a clockwise direction, its pawl 128 will, by its engagement with the ratchet 124, rotate the latter and the shaft 118 clockwise, but that when either gear is rotated contraclockwise, its pawl 12S will slide over the teeth of the ratchet 124 which will be held against rotation by a spring pressed locking pawl 134 pivoted to the adjacent face of the arm 114 of the bracket 112.

For rotating the gears 120 two sets of rack teeth 136, Fig. 1, each set consisting of three teeth, are provided upon the upper surface of the handle plate 25, one beneath each of the gear wheels 120 so as to engage the latter and rotate them as the handle 26 is oscillated. With the parts in the position shown in Fig. 5, if the handle 26 be swung to the right, the three rack teeth 136 beneath the left hand gear 120 will rotate the latter clockwise and with it the shaft 118 and unit wheel of the counter, while the three rack teeth below the right hand gear 120 in said figure will rotate the latter contra-clockwise without causing any operation of the shaft 118. If the handle 26 be now swung back into the position shown in Fig. 5, the three rack teeth 136 below the right hand gear 120 will rotate the latter clockwise thus actuating the shaft 118 and the unit wheel of the counter, while the rack teeth beneath the left hand gear wheel 120 will rotate the latter contra-clockwise without operating the sha-ft 118. As the ratchet wheel 124'is provided with thirty teeth and three rack teeth are provided for rotating each of the gears 120, it will be apparent that each time that either gear is rotated clockwise the unit wheel of the counter will be turned one-tenth of a complete rotation.

1t is deemed unnecessary to describe the connection, between the various counter wheels ywhereby each counter wheel in Y effecting its tenth increment of a complete rotation rotates the one of the next highest denomination an increment equal to one-tenth of a. complete rotation. Such arrangements are well known and require no explanation here to be fully amderstood. The counter wheels are contained in a casing 138 provided with a. glass window 140 through which the numerals on the counter wheels are clearly observable. Preferably, the sets of rack teeth 136 are so disposed relatively to the wheels 120 that the counter will be caused to register by any movement Y of the handle 26 sutlicient to establish com- -the handle 26 has been initiated in either direction, reverse movement of the handle be prevented until it has completed its full stroke or until the valve has been turned sul'liciently to establish communication between the container which is to be discharged and the nozzle 22 and also sui'liciently to cause the counter to register. Means are aecordingly provided to that end, said means in the illustrative embodiment of the invention shown comprising rack teeth 142 provided on the periphery of the handle plate 25, see Fig. 5. A pawl 144 is pivoted at 146 on the base of the bracket 112, the swinging movement of said pawl in either direction being limited by stops 148, 150. The distance from the pivot 146 to the operative end of the pawl is greater than the distance from said pivot to the base of the space between any two of the teeth 142 when said space is directly opposite said pivot. As a result, the parts being in the position shown in Fi g. 5, if the handle 26 be swung contra-clockwise, the rack teeth 142 will engage the pawl 144- which will thus incline slightly to the left, thus permitting free movement of the handle 26 contra-clockwise but preventing by its engagement with Said rack teeth any reverse movement of said handle. When in the continued movement of the handle 26 in a contra-clockwise direction, the rack teeth 142 h ave passed out of engagement with the pawl 144, reverse movement of the handle, that is to say, movement in a clockwise direction, is no longer prevented. In such movement, the rack teeth 142 engage the pawl from the other side and said pawl being thus inclined to the right permits free movement of the handle 26 in a clockwise direction, but so long as the pawl is in engagement with the rack teeth, movement of the handle 26 contra-clockwise will be prevented and can only take place after the handle has been moved suliiciently far in a clockwise direction to carry the rack teeth 142 out of engagement with the pawl 144.

By unscrewing screws 113, Fig. 5, the counter supporting arm 114, Fig. 6, can be readily removed, and then on removing the screws 25 25, Fig. 2, the plate 25 can be withdrawn from under the overlapping edges of the heads 48 of rods 44. As these heads 48 do not overlap the edges of the core 12, the latter can now be removed to give access to the valve chamber and adjacent parts and to said core. It will thus be 'seen that all parts of the apparatus are readily accessible for cleansing or for any other purpose.

It will be apparent that if it is not desired to vary the quantity of liquid dispensed, the reduced circular portion 58 of the socket member 60 may be shortened so that it shall terminate substantially Hush with the lower surface of the plug 56 or of the inner surface of the top wall of the containers S and 10. ln such case, and also in the case where the chamber 6 is caused to communicate directly with a source of supply, the containers 8 and l() will always be filled to their full capacity. Any size container may be used in accordance with the present invention. lt will be apparent that a tube communicating with any continuous source of supply of the liquid to be dispensed could be inserted in the socket 6 in the place of the neck of a bottle.

While vents 42, l2 have been provided in the illustrative embodiment of the invention shown, such vents are not essential as, owing to the fact that the top walls of the containers 8 and 10 are on a level with the top walls of the chamber G, any air con. tained in the containers 8 or 10 can escape freely, even when the containers are filled to their full capacity as will be apparent to those skilled in the art without further eX- planation. lf desired, the top walls of the containers S and l() may be caused to incline slightly upward toward their point of junction with the plug 12 to facilitate such escape of the air.

lt is not deemed necessary to give any further explanation of the mode of operation of the specific apparatus shown as such operation will be perfectly clear to those skilled in the art from the description above given of the apparatus itself.

lt will be apparent that it is not indispensable that all of the features of the invention be used conjointly since they may be used to advantage separately in various combinations andI sub-combinations. It will also be understood that while the invention is herein described as embodied in the details illustrated, it is not to be considered as circumscribed or limited to these details, or any of them, but it may be variously modified within the true scope of the invention which is definitely set forth by the claims.
